1. Define what you are trying to solve

A supplement should not substitute for evaluation of persistent pain, swelling, weakness or loss of function.

2. Read the actual label

Ingredient names alone are not enough. Check amounts, serving size, proprietary blends and allergens.

3. Compare evidence at the dose level

Ask whether the product amount resembles the amount studied, not merely whether the ingredient appears in research.

4. Check interactions

Botanicals and vitamins can interact with medicines and medical conditions.

5. Compare real cost

Use total checkout price and cost per day.

Health note: Supplements are not a substitute for diagnosis or treatment. Talk with a clinician or pharmacist when medication interactions or medical conditions are relevant.
